Benoni Defense

Overview

The Benoni Defense (1. d4 Nf6 2. c4 c5) is a sharp, unbalancing opening where Black immediately challenges White's d4-pawn. After 3. d5, an asymmetric pawn structure arises with Black having a queenside pawn majority and White holding a central space advantage.

Key Ideas

• After 3. d5, Black plays ...e6 and ...exd5 to create a mobile queenside pawn majority.
• Black's main plan involves ...d6, ...g6, ...Bg7, and pushing the b- and a-pawns on the queenside.
• White has a strong passed d5-pawn and often seeks e4-e5 to cramp Black's position.
• The position is highly tactical and requires precise play from both sides.
